Take a full-length Practice Test (Beta)

This is your typical math section that involves a math simplification/calculation question. You'll need to understand number properties -- how do you combine expressions that involve exponents? How do you know if certain expressions can be positive or negative? How is squaring a fraction different from squaring an actual number?

In geometry and coordinates - you'll need to find the value of certain angles, or the length of certain segments with only the available information given.

Perhaps the more difficult questions are the ones that involve a lot of fractional algebra, rate word problems, mixtures, and combination/permutation related math questions.

But before you can attack these more difficult math questions, you need to solidify your quant fundamentals and equip yourself with tactical strategies that help you solve math questions in as little time as possible. The key is efficiency so you can use that extra time on the extra hard questions.
